In the first embodiment, the size of the instruction memory does not change if the functions are the same even if the capacities differ,
Focusing on the fact that the size of the data memory for storing system data, user data, and intermediate results of processing greatly changes, means for storing the number of equipment that can be mounted in a key telephone main unit capable of selecting a hardware configuration, The program is configured to have means for storing the position information of the memory necessary for performing the exchange process. The program does not directly refer to the data memory, but performs processing by reading the position information of the memory stored in these storage units and the number of facilities that can be handled by the memory. The key telephone main unit having the same function can deal with the telephone exchange processing relating to the new number of facilities only by changing the storage contents (the number of facilities) without changing the program.

Further, the number of mountable facilities can be automatically calculated from the device configuration such as the amount of memory mounted and the number of time switch circuits, or can be defined as input information from an external storage medium such as a ROM or HD. It is possible to automatically or manually make the same program correspond to various capacities.

Are respectively connected to extensions 12-1, 12-2, and 12-3, the interface 14 is connected to the relay console 13, and the trunk circuits 15-1 to 15-4 are respectively connected to the office line 16-.
1 to 16-4.

FIG. 2 shows the arrangement of the setting information on the RAM 19 in FIG. 1, and stores the number of facilities and the position information of the memory necessary for performing the exchange processing on the number of facilities. As shown in FIG. 2, a predetermined address on the memory includes an area 21A for storing the number of facilities such as the maximum capacity of analog extensions, analog office lines, and ISDN office lines, and an analog extension, an analog office line, An area 21B for storing a head address of a data area such as ISDN station line related data and the like whose required size changes depending on the number of facilities, and a data allocation area 21C for storing actual data are arranged.

In this embodiment, the area 21A for storing the number of various facilities described above, the area 21B for storing the head address of various data areas, and the head address of the data allocation area 21C for actually storing data are stored in a ROM.
By defining the program area on the program area 18 in advance, it is possible to refer to the number of necessary facilities or the address of the data area at the time of operation.

FIG. 3 shows a flow of a process of registering an analog extension as an example of a flow of a process using the RAM 19 described above. When registering an analog extension, it is determined whether the number of lines is within the range of the number of lines allowed in the system (step S1). in this case,
The determination is made by referring to the area storing the maximum number of stored analog extensions and comparing the value set in the area with the number of analog extensions already set. If it is out of the allowable range, error processing is performed (step S5). If it is within the allowable range,
It is necessary to derive a storage area for data to be registered. For that purpose, first, the storage area of the analog extension related data is read out with reference to the area storing the head address of the analog extension related data (step S2). Next, data write position information to be registered is calculated from the number of analog extensions already registered (step S3), and the registered data is written to that address (step S3).

FIG. 4 is a flowchart showing the flow of processing for automatically determining the maximum value of the number of various types of equipment and data storage location information. Since the amount of memory to be implemented is often adjusted depending on the number of lines to be provided, here we will consider deciding from the size of the implemented memory,
The present invention is not limited to this, and may be determined by referring to the number of circuits of the time switch and the number of mounted interface boards.

Since the number of facilities and the storage area for data are always required for the operation of call processing, they must be set when the system is started. Therefore, first, when the system is started, the amount of installed memory is checked, and the number of facilities is determined based on the size. Here, as shown in FIG.
Only the two types of facilities with Byte as a boundary are determined.
That is, it is determined whether or not the memory size is equal to or larger than 2 MBytes (step S10), and in the case of YES, the maximum number of analog extensions: 300, the maximum number of analog office lines: 150, and the like are determined (step S11). ). If the number is less than 2 MBytes, the maximum number of analog extensions is set to 100, the maximum number of analog office lines is set to 50, and the like (step S12). Note that the above determination is merely an example, and a criterion may be defined according to the actual memory configuration. The determined number of facilities is set in an area defined in advance for the type of data. After the number of equipments is determined, the size of the data area required for the circuit switching processing of the number of equipments is calculated (step S13), sequentially allocated from the head address of the predefined data storage area, and the memory location information is assigned. Determine (step S14). The determined position information is set for an area defined in advance for the type of data (step S15).

By referring to the setting information set in this way in the above-described processing, it becomes possible to provide a key telephone main unit having various lines with the same software.

In the present embodiment, a method has been described in which the number of facilities and the location information of the memory required for the circuit switching processing are automatically determined from the equipment configuration and set on the memory. It is also possible to take a means for referring to the position information from the processing program as the fixed information written in the ROM or the like.

FIG. 5 is a block diagram showing the case where the number of facilities and the location information of the memory are set in the ROM. Here, data that depends on the number of lines is stored in an RO
M, the ROM of the processing program part
It is possible to provide a key telephone main unit with various numbers of lines simply by replacing the ROM in which the data is defined while keeping the same. FIG. 5 shows an example in which the number of facilities and the position information of the memory are written in the ROM in advance, but such information is set in advance on an external storage medium other than the ROM, such as an HD or a memory card. No problem.

According to the above-described first embodiment, it is possible to provide a key telephone main unit that is compatible with different capacities while using the same software, and requires a memory optimized for each. . In other words, even when multiple capacity models are supported, key additions and modifications that require software modification only need to be performed once, greatly improving development efficiency and fixing time, and reducing costs. A main device can be provided.

The main device 1 includes an extension interface unit 31, an outside line interface unit 38, a processing group selection unit 34, an intermediate table setting unit 33, a priority determination unit 36, a processing execution unit 37, and a database 35. Database 35 is intermediate table 3
5-1 is provided.

As an example of the second embodiment, when deciding the priority of the process based on the process type and the terminal status, the extension terminal 32-1 dials a special number and the extension terminal 32-2, 3
A process when a call is transmitted from the extension terminal 32-4 to the extension terminal 32-5 during the simultaneous incoming call process to 2-3 will be described. In the database 35 of the main device 30, as shown in FIG.
It is assumed that there is a processing priority table corresponding to the processing type and the terminal status corresponding to the system, which is set at the time of system startup. It is also assumed that the database 35 of the main device 30 has a state management table for managing terminal states.

FIG. 8 shows an example of the processing flow of the main unit 30 when receiving a message. After the extension terminal 32-1 is off-hook, the simultaneous incoming call special number is dialed. When the extension interface unit 31 receives a dial signal (message) from the extension terminal 32-1 (step S20), the processing group setting unit 34 selects a dial analysis process. That is, it is determined whether or not there is a dial analyzer to be executed (step S21).
Registers the dial analysis process of the extension terminal 32-1 in the intermediate table 35-1 of the database 35 as the scheduled execution process (step S22). Further, information necessary for executing the dial analysis process, that is, the received dialed number here is set in the intermediate table 35-1 (step S23).

FIG. 9 shows the configuration of the intermediate table 35-1 at this time. The procedure for executing the processing registered in the intermediate table 35-1 will be described below with reference to the flowchart in FIG. The main device 30 sets a scheduled process monitoring timer. When the scheduled process monitoring timer times out (step S30), the priority determination unit 36
Checks whether there is an execution scheduled process in the intermediate table 35-1 (step S31).

If only the dial analysis process of the extension terminal 32-1 is registered in the intermediate table 35-1, as shown in FIG. 9, the priority determination unit 36 determines the most recent from the priority table corresponding to the process type and the terminal status. Determine the priority task (step S
32), it is determined to execute the dial analysis process of the extension terminal 32-1. Then, the process execution unit 37 executes a dial analysis process based on the information set in the intermediate table 35-1 (Step S33), and executes the intermediate table 35-
From step 1, the part of the executed dial analysis processing of the extension terminal 32-1 is deleted (cleared) (step S34).

When the dial analysis process of the extension terminal 32-1 is executed, the extension terminal 32-1 is transmitting a call,
-2 and 32-3 are registered in the state management table as an incoming call. FIG. 11 shows an example of the state management table of the extension terminals 32-1, 32-2 and 32-3 after the extension terminal 32-1 has executed the dial analysis process. After the execution of the analysis process, the process group selection unit 31-3 determines whether there is a process to be newly executed as a result of executing the process (step S35).

When there is a process to be newly executed, the process group selecting unit 34 performs the LED lighting, the LCD display and the ringing process for the extension terminal 32-2, and the process to the extension terminal 32-3 based on the result of executing the dial analysis process. LED lighting, LCD display and sound processing are selected. Then, the intermediate table setting unit 33 registers the processing group to be newly executed selected by the processing group selecting unit 34 in the intermediate table 35-1 (Step S36), and also stores information necessary for executing the processing in the intermediate table 35-. It is set to 1 (step S37). FIG. 12 shows the contents of the intermediate table 35-1 in this state.

Then, the priority determining unit 36 checks again whether or not there is a scheduled process in the intermediate table 35-1 (step S31). When a plurality of processes are registered in the intermediate table 35-1 as shown in FIG. 12, the priority determining unit 36 executes the ringing process of the extension 32-2 with reference to the tables of FIGS. To determine. Then, the process execution unit 37 executes the ringing process of the extension terminal 32-2 based on the information set in the intermediate table 35-1, and performs the ringing process of the extension terminal 32-2 from the intermediate table 35-1. to erase. When the ringing process of the extension terminal 32-2 is executed, a ringing signal is transmitted from the extension interface unit 31 of the main device 30 to the extension terminal 32-2, and the extension terminal 32-2 is operated.
2. The extension rings. After that, the priority determination unit 36 sets a scheduled execution monitoring timer (step S38).

Thereafter, in the same procedure, the extension terminal 32-3 is sounded, the LED of the extension terminal 32-2 is turned on, the extension terminal 32-4 is off-hook, and then the extension terminal 32-3 is turned off.
Dial the extension number 5. When the extension interface unit 31 receives a dial signal from the extension terminal 32-4, the processing group selection unit 34 selects a dial analysis process. Then, the intermediate table setting unit 33 registers the dial analysis processing of the extension terminal 32-4 in the intermediate table 35-1 as the scheduled execution processing. Also, the received dial digits, which are information necessary for executing the dial analysis process, are set in the intermediate table 35-1.

Thereafter, when the scheduled process monitoring timer times out, the priority determining unit 36 sets the intermediate table 35
-1 to see if there is a scheduled process,
It is decided to execute the dial analysis process of 2-4.

Thereafter, similarly, the dial analysis processing of the extension terminal 32-4, the ringing processing of the extension terminal 32-5, and the extension terminal 32-4
-3 LED lighting, extension terminal 32-5 LED lighting, extension terminal 32-2 LCD display, extension terminal 32-3 LC
The process is executed in the order of D display and LCD display of the extension terminal 32-5. Thereby, the extension terminal 32-4 to the extension terminal 3
The transmission processing to 2-5 can be processed without waiting for a long time.

Next, as a modification of the second embodiment, a case where the priority is determined based on the number of processes waiting to be executed will be described. FIG. 13 is a diagram illustrating an example of a system configuration according to a modification of the second embodiment of the present invention. The main apparatus 30 is different from the above-described second embodiment in having a counter 40. The database 35 has a priority table corresponding to the number of processes waiting to be executed. FIG. 14 shows an example of the priority table corresponding to the number of processes waiting to be executed.

When registering a process to be executed in the intermediate table 35-1, the intermediate table setting unit 33 counts up the counter 40 by the number of registered processes. Process execution unit 3
The counter 7 counts down the counter 40 when executing the processing to clear the intermediate table 35-1. The priority determining unit 36 determines a process to be executed with reference to the counter 40 and a priority table corresponding to the number of processes waiting to be executed.

Note that the present invention is not limited to the above embodiment. For example, the table configuration and the like may be determined at any time according to the specifications. For example, the priority determination unit may determine a process to be executed based on a complex relationship between the terminal state and the number of processes waiting to be executed. Also, the priority table corresponding to the terminal status is not limited to the table corresponding to the system,
For example, a table corresponding to a terminal may be used. Alternatively, the registration status of the intermediate table may be checked each time a message is received, instead of monitoring whether or not the scheduled execution process has been registered in the intermediate table using the scheduled execution process monitoring timer. In addition, only in the case of a specific process such as a simultaneous incoming call, information necessary for the execution of the process is temporarily set in the intermediate table, and the execution order of the process is changed, and the normal outgoing process is processed without using the intermediate table as before. May be executed.

According to the above-described second embodiment, if necessary, judgment processing necessary for executing the next processing is performed first, and processing that does not affect the execution of the next processing and takes a long time is executed. By setting necessary information in the intermediate table and postponing it, the execution order of processing can be uniquely changed according to the priority, so that the serviceability of the system can be improved.

[0044]

According to the first aspect of the present invention, even if the capacity is changed, the same software can provide a telephone exchange function having a different maximum number of lines. Further, according to the second invention, the judgment process necessary for executing the next process is performed first if necessary, and the process which does not affect the execution of the next process and takes a long time is the information necessary for the execution. Since the setting is made in the intermediate table so as to be postponed, it is possible to provide a telephone exchange device with improved system serviceability.
